Abstract : The purpose of the informal test reported in this QSTR was to analyze Magnavox's interpretation and use of the CALS standards in transferring CALS Class II IGES data. Magnavox used its CALS Technical Data Interchange System to produce data in accordance with the standards and delivered it to the CTN technical staff on a floppy disk. This test was conducted in conjunction with the Cincinnati IGES User Group meeting hosted by the Air Force CALS Test Bed (AFCTB). The files were created by Magnavox and sent to International TechneGroup Incorporated where the files were modified to meet MIL-D-28000A Class standards. It should be noted that MIL-D-28000A is only a draft at the time of this test. This test was run in conjunction with the Cincinnati IGES User Group meeting that was hosted by the AFCTB.
